Final answer:
Recommendations for the PU, NU, and MU must be submitted within three years from the date of action, but the specific time frame for the award to be made after recommendation is not provided and should be checked with official sources. The President must also seek congressional confirmation for troop deployment within 48 hours and approval for actions beyond 60 days.
Step-by-step explanation:
The Presidential Unit Citation (PU), Navy Unit Commendation (NU), and Meritorious Unit Commendation (MU) are all distinguished awards given to units of the U.S. armed forces for exceptional performance in battle or extraordinary service. Recommendations for these honors must be submitted within three years of the date of the action or service for which the commendation is being given. The criteria for the time frame in which the award must be made after recommendation were not provided in the question, and they might vary or be subject to changes in military policy or legislation. Therefore, it is important to consult the current Department of Defense or individual military service branch guidelines for the most accurate information.
It is also important to note the broader context of military actions. According to given information, when the President of the United States deploys troops for hostile reasons to other countries, they must notify Congress within 48 hours and seek congressional approval for actions extending beyond 60 days. This provides a framework for checks and balances within the U.S. government regarding the use of military force.
